William Douglas, 10th Earl of Angus was a Scottish nobleman. He was the son of William Douglas, 9th Earl of Angus (1533–1591). He was a direct descendant of King James I through his paternal grandmother, Agnes Keith, a daughter of William Keith, 3rd Earl Marischal.

Francis Stewart, 5th Earl of Bothwell, was Commendator of Kelso Abbey and Coldingham Priory, a Privy Counsellor and Lord High Admiral of Scotland. He was a notorious conspirator who led several uprisings against his first cousin, King James VI, all of which ultimately failed, and he died in poverty in Italy after being banished from Scotland. Francis's maternal uncle, the 4th Earl of Bothwell, was the chief suspect in the murder of James VI's father, Lord Darnley.
